Portuguese Sea, a sea of accounting.

Lusophone memories lie embedded across the Malabar Coast

where the Arabian Sea and Indian Ocean meet the Tagus River

at estuaries, around archipelagoes, at the confluence of the River Periyar.

Here, one walks the Mar Portugues in all its violent ruin

forgotten but not disappeared

enmeshed in the red clay and forbidding stones

of Castello construction at Kannur, Cochin, Kollam, Cranganore

At Fort Aguado, Goa, the Oublie stands a dark reminder

of a sea of accounting
